The M774 DSO is a member of Etc Measuring Lab 3 (EML3) family.

The M774 is a dual channel USB oscilloscope compatible with USB 2.0 and USB 1.1 interface. The computer is isolated up to 500Vp from the measuring circuits of the oscilloscope. The ease of installation and connection to computer makes M774 extremely portable. The device is connected to computer using standard USB 2.0 cable and is powered directly from computer. The maximum power consumption of 2.35W makes this instrument highly usable with battery-powered notebooks.

The device inputs are accessible via BNC connectors and are compatible with standard probes (with minimum of 30 pF compensation range). Internal storage (1M per channel) is used as a fast data buffer to store a measured waveform.

The software is the part of the M774 package. In order to keep the device functions up to date, there is a latest version of software available on our website free of charge. The software provides you with possibilty to fully operate the device. All standard features of modern DSOs (hold acquisition process, hold-off, zoom etc.) and many more (saving/loading the waveforms for future use, export to clipboard, printing the results together with scope settings) are available.

The fast data transfer offers extremely rapid display refresh (creating an impression of analog instrument).

Four standard acquisition modes (AUTO, NORMAL, SINGLE, MANUAL) are available. The trigger event is created by dual level triggering system equipped with digital pulse length filter and event counter on each level. The channel A, channel B and the external trigger input can be activated as a triggering system source. The threshold of channel A and channel B trigger is settable in whole range of scope screen. The threshold of external trigger is fixed to about 1.5V and is TTL and CMOS compatible. This sophisticated triggering system allows displaying waveforms with very complicated trigger events (i.e. selected row of the video signal).

The time base in 1:1 display mode (no zoom) is settable from 5ns/div to 100ms/div in sequence of 1-2-5. It is possible to set the time base from 625ps/div to 204.8s/div using different zoom settings.

Installation guide in paper form and detailed user’s guide on CD are part of the M774 package. The tool tip help makes software easy to use.

Software works under Windows 98SE, Windows ME, Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8 and Windows 10(1903) operating systems. The oscilloscope screen can be resized according to your monitor resolution (minimum 800x600).

Two optional software packages are available: M770 Development kit, which will allow you to write your own application using the device and the M770 Roll mode, which will turn the oscilloscope into data logger.
